This study explored the dynamics of power relationships in secondary science methods courses taught at an urban university in Southern California for credential candidates. Data collection extended over 10 academic semesters. Employing frameworks of power, self-study, and critical pedagogy, the study analyzes the multifaceted and intricate roads (or multimirrored reflections) of an instructor on her way to becoming a transformative intellectual. Findings suggested that power sources and their use may vary according to the credential candidates' needs and the demands and perceptions of the different tasks performed in class. Perceptions of the instructor's goals and perceived attitudes during classroom tasks seemed to relate to power shifts ultimately influencing classroom dynamics. The major implications of this study was to reemphasize the acute need for instructor self-studies in science education as a way of improving practice and fulfilling the demands of the changing and challenging science credential candidate population as well as their K–12 students. © 2007 Wiley Periodicals, Inc.
